Question 2

What is a Cladogram used for?

Answer 2

Showing the evolution over time of species

Question 3

Trophic level names

Answer 3

Producers, primary, secondary, tertiary, quaternary

Question 4

What type of relationship/s are +/-

Answer 4

Predation and parasitism

Question 5

What are abiotic factors?

Answer 5

Factors which are non-living or physical what affect an ecosystem/environment . (Sun, rain, soil etc)

Question 6

What are biotic factors?

Answer 6

Factors which are living and affect an ecosystem/environment, such as organisms.

Question 7

What is Population density?

Answer 7

Number of organisms in a given area. (Same species)

Question 8

What is a Transect?

Answer 8

A straight line set over a certain distance to measure the number of organisms or topography.

Question 9

What is a quadrat?

Answer 9

A randomly placed square in a set area to get an estimated population.

Question 10

What is the capture and recapture method?

Answer 10

It is a method for getting an estimated population of a certain species. This was done by capturing a sample, marking them releasing them, then recapturing them. Followed by a calculation.

Question 11

What is the equation for the capture and recapture method?

Answer 11

Sample 1 multiplied by sample 2, divided by marked in sample two = est pop

Question 12

What is the equation for photosynthesis?

Answer 12

6CO(2) + 6H(2)O —-> 6O(2) + C(6)H(12)O(6)

Question 13

What is primary succession?

Answer 13

Primary succession is the succession of new organisms in a area which has absolutely no life. (In areas like sand dunes, lava flow and glacial run)

Question 14

What is secondary succession?

Answer 14

It is the Succession of an area which was destroyed, but still has soil and some organisms left. (Caused or left by fires, flood etc)

Question 15

What type of curve does a r-selected species follow?

Answer 15

A J-curve, quickly growing above the carrying capacity.

Question 16

What is the carrying capacity?

Answer 16

The carrying capacity is the limit which an ecosystem can support a population through its resources.

Question 17

What curve does K-selected species follow?

Answer 17

An S-curve, fluctuating above and below the carrying capacity.

Question 18

What does the acronym PANDA PAW represent and stand for?

Answer 18

PANDA PAW represent the factors which affect carrying capacity.
P-predator, a-availability of resources, n-nutrient supply, d-disease, a-accumulation of waste, p-phenomena, a-abiotic factors, w-weather

Question 19

What is biomass?

Answer 19

The dry weight of an organism in a given area

Question 20

How much energy is transferred between organisms?

Answer 20

On average 10%, with a little variation depending on ecosystem and environment

What is needed for fossilisation to occur?

Answer 21

Heat, pressure and time

What are fundamental niches?

Answer 22

The theoretical set of conditions which organisms live by

Question 23

What are realised niches?

Answer 23

The real conditions which organisms live by

Question 24

What are keystone species?

Answer 24

-A species which has an unproportional effect on an ecosystem based on biomass

Question 25

What is an umbrella species?

Answer 25

• species which others relie on

- tied to its geographical range

Question 26

Answer 26

-species which are sensitive to change (immediately show signs of change in ecosystems)

Question 27

What are foundation species?

Answer 27

-species which play a role in creating and maintaining habitat

Question 28

What are ecosystem engineers?

Answer 28

-species which modify, create and maintain habitat/ecosystem

Question 29

What are the three types of population distribution?

Answer 29

Random, clumped and uniform
